PROCESS AND APPARATUS FOR MAKING PLATE, WINDOW, OB WIRE GLASS.

Specification of Letters Patent.

Patented Feb. a, 1909.

Application filed September 24, 1907. Serial No. 394,318.

To all whom it may concern:

Ben known that I, Jun-2s J. QUERTIN- Mox'r, a citizen of the UnitedStates, residing at Point Marion, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inProcesses and Apparatus for Making Plate, ll'indow, or lVire fllass, ofwhich the'following is a specification.

lily invention relates to the manufacture of glass, and is applicable tothe production of plate, window or sheet glass of all varieties whetherV\'l1(l or not.

The present matter has to do only with the broad general principle uponwhich my in vention is based, namely, in making plate, window or sheetglass of all varieties in which one side is already finished or polishedand not required to be further acted upon by a tool and finished byanypolishing action. 4 y

The said invention is herein cnbodied in suitable mechanism for carr ingthe same into practice, the mechanism are illustrated and describedbeing merely one of many forms that may be adopted.

In the following description and in the annexed drawings I shall avoid,as far as practicable, all unnecessary details in order toprecludeuncertainty or mistake as to the leading and important of theinvention and of the machinery for carryin out that invention, or inother words; shall describe and illustrate a vex? simple embodiment of,the invention whic 1 Tactical tests have demonstrated to be satisfactoryand cfiicient.

Briefly stated, the invention consists in the manufacture of plates,sheets, or films of glass of any desired form having one side or surfacehighly polished without the necessity of having any polishing toolsapplied thereto.

Referring now to the annexed two SllQQir of drawings: Figure 1 is a sideelevation partly in section of a glass melting furnace with means forhandling the moldin While dipped into the molten glass; ig. 2 is alongitudinal section of the dipping frame with an ordinary lass plateformed therein: Fig. 3 is a longitutinal section of the dipping framefor making Wire glass with the difler- Fig. l is a longitudinal{superihmus molten glass wil freely i uniformly flow off from the g themold without straining or pulling the ig. G l same.

out parts separated; section on line -i-l of Fig. 5 hh the partsassembled and the glass plate formed there in; fig". 5 is :1. plan viewof Fig. 1 )artly broken away and the glass removed,

features or elements frames is a transverse section online 6--fi of Fig.5 with glass plate formed therein; Fi 7 IS a ransverse section on line7-7 of Pig. 2.

Similar reference characters indicate the same parts in the severalfigures of the drawings.

Referring to Fi 1 of the drawing, 1 represents a sections view of anordinary glass melting furnace while 2 is anywell nown form of overheadsupporting track. 3 is a trolley wheel moving back and forward on track2, said wheel carrying a. depending and flexible supporting means 4 fromwhich is hung by pivotal joint 5 a horizontal operatiug rod 6. Attachedto one end of said rod 6 by means of flexible chains or cables 7, asindicated, is a dipping frame or mold 8 which may be of any shape orform either in depth or contour so-as to be of the exact shape which itis desired the'finished roduct should assume.- Said flexible chains orcables 7 are arranged and fastened to the dipping frame so that theframe will be held in a horizontal position as indicated for thereasonsthat wil be hereinafter explained.

The preferred. form of frame or mold for making the plate of glass isshown in Figs.

2-7 and consists of a bottom 9 having prefcrahly integrni or fixed endsections 10, 10, to which are attached the eyes 11 or other means forconnecting the supporting chains or cables as shown in Fig. 1. Attachedto the bottom 9 and on each sideby means of corner pins 12, sec 1*" 5,'arc upper and lower side pieces 13 an 14, see Figs. 3,5, 6 and 7,thereby forming a shallow dipping frame or tray. Attached to and passingthrough the lov'ver side which tit into correspom ing'rccesses in theunder side of the up or pieces 14, as shown in Figs. 6 and 7, an whosefunction visill he heir-inafter explained. i

- '"ifhe inner side walls'lfi of the frame, see Figs. 2 and 4, may beslightly inclined as shown in Fig. 2. for easily removing the plat-9 ofglass after being formed or they may he vertical as shown in Figs. 3 and4.

5 The upper surfaces of the end and side pieces l 10 and. 14 are innerwalls of frame body of glass in ieces are pins 15 held in the depressedsection of the frame. I

The mode of carrying out the process and applying the apparatus is asfollows: When it is desired to make plain plate or window glass a frameof the proper dimensions and assembled as shown in Figs. 2 and. 7 isproperly poised on a traveling rod supported as indicated in Fig. 1.Assoon 'as the perfec'tly clean frame 8 is in the furnace and over themelted glass it is gradually dipped into the glass when the same willflow slowly over all the sides and entirely dis lace all the air andfill every portion of the epresscd section of the frame. After the samehas beenfilled with molten glass it is slowly raised therefrom andpermitted to pause in its movement out of the furnace a short time overthe melted glass and permit all the superfluous lass, owing to thebeveled or outwardly inclined top edges of the sides of the'frame, toreadily flow away from the glass The frame ils then slowly and easilywith .drawn from the furnace by means of rod 6 and overhanging trolleysup ort 2, and the glass permitted to cool. It lias been found that theupper surface of the glass when permitted to be formed with theconditions as indicated above, is erfectly smooth and even and with sucha uster that no furt ier o ishing or other operation is required tofinish this side of the plate. The plate of glass 17 may be removed byeither turning over the frame or removin one side of ieces 1,3 and 14and slidin t is cooled plate om the frame. After t is the lower orbottom side of the plate of glass may be finished or polished up whenthe glass is read for the market.

W ile I have described that the frame 8 may be dipped into the moltenglass for the urpose o filling the same I wish it to be .istmctlyunderstood that after the frame has been inserted into the furnace andover the molten glass I may provide a ladle for taking the molten lassand pouring into the frame and thereaf ter repeat the operation asalready described.

In making Wire glass one separates the frame as indicated in Fi 3 byremoving the upper pieces 14 on each side, then stretch a-proper size orsection of wire mesh 18 which meshes from one set of pins 15 on one sidepiece 13 to the other side as indicated in Figs. 5 andfi. The top sidepieces are then replaced as indicated and the frame is dip ed or filledwith molten glass and after coo ing can be made to go through the sameoperations as already described in connection with'Figs. 2 and 7.

From the foregoing description of the methodand apparatus it will bereadily seen that I have invented a process and means for carrying outthe same wherein plate, window or sheet glass can be easil and cheaplymanufactured and one without departing from the spirit of my' inventionand accomplish the same results.

Nhat I claim as new and desire to secure by Letters Patent is asfollows 1. The method of making plate, window or sheet glass whichcomprises the introduction of molten glass to freely overflow the upperinner edge of the mold until its upper surface corresponds to the planeof the top ed e of the frameor mold and carefully drain off thesuperfluous molten glass and then cool said body of glass in said frameor mold.

2. The method of making plate, window or sheet glass which comprises theintroduc tion of molten glass in a shallow frame or mold and permittingthe upper surface of the glass to freely and uniformly overflow the up:

er inner edge of the mold until its upper sur face corresponds to'theplane of the top edges of the frame or mold and completely drain off thesuperfluous molten glass then cooling said body of glass in said frameor mold and finally polishing the lower surface of the glass which iscontiguous to the bottom of the frame or mold. V

3. The method of making plate, window orsheet wire glass whichcomprisesthe supporting of wire netting between the bottom and topplanes of a shallow mold or frame, introducing molten glass into thesaid frame or mold and permitting the upper surface of the molten glassto freely and uniformly overflow the upper inner edge of the frame untilits upper surface corresponds to the plane of the top edges of the frameand completely drain 0 the superfluous molten glass and then cool saidbody of glass in said frame or mold. V
